Hike the Aonach Eagach Ridge
Glen Coe, Scotland
Though no ropes or other gear are required, you don’t want to take this hike lightly. It’s total of 5.75 miles, 2 of which have steep, knife-edge drop-offs on either side. It is full of tough terrain and daunting precipices, so you must be wary of not making a mistake, and in the winter time climbing gear is absolutely necessary. When you’re not afraid of taking your eyes off every step you make, you can enjoy the rugged Scottish Highlands, including Ben Nevis, the tallest peak in the British Isles.
